DAVIS MARINSKY, OF NEW YORK, N. Y., ASSIGNOR TO NEW YORK BUCKLE COMPANY,

OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

BUCKLE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, DAVIS MARINSKY, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Buckles, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. 1

This invention relates to buckles, and the object thereof is to provide an improved device of this class which is particularly designed for use in connection with belts, suspenders and trousers straps and which may be used in connection with straps employed for many other purposes; and With this and other objects in view, the invention consists of a buckle constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the fol lowing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure l is a plan view of one form of my improved buckle; Fig. 2 a section on theline 22 of Fig. 1; Fig. 3 a view similar to Fig. 2, but showing a method of using the buckle; Fig. Ara view similar to Fig. 1, but showing a modification; Fig. 5 a'section on the line 55 of Fig. 4, but showing a method of using the buckle, Fig. 6 a section on the line 6-6.0f Fig. 4, but showing the strap in position as shown in Fig. 5; and,

Fig. 7 a view similar to Fig. 3 but-showing a modification.

In the practice of my invention as show in Figs. 1 to 3, inclusive, I rovide a bu comprising a plate a which is stamped fromany suitable metal and which is preferably rectangular and slightly oblong in form but which may be of any desired shape.

In one side of each portion of the plate a is formed a transverse slot a and parallel therewith and centrally of the remaining portion of said plate is a raised bridge member a preferably formed by being stamped from the material of said plate, which portion forms a corresponding transverse slot a 1n said plate as clearlyshown in Figs. 2 and 3. I also provide a rock dog?) which is also stamped from a sheet of metal and comprlses a front nose piece or tongue 6 and a back transverse head 6 and the front nose piece or tongue 6 adapted to be passed forwardly beneath the bridge a or between said bridge and, the plate a, while the transverse head 6 is extended laterally and made longer than said bridge and cannot be passed thereunder by reason of the shoulders 1) formed by the projecting end portions of said head. i i

The shape of the rock dog b transversely of the bridge a is that of an ogee curve and the middle portion of said rock dog wher in position for use curves downwardly beneath the bridge a", and this forms a transverse groove in the top of said rock dog in which said bridge operates. i

The transverse head 6 of the rock dog is provided at its opposite ends and adjacent to the shoulders 6* with downwardly directed ears If both of which are indicated in dotted. lines in Fig. 1 andone of which is shown in full lines in Figs. 2 and 3, and these ears- 6 form pivots or fulcrums on which the rock dog operates, said operation being similar to that of a lever'.

The nose or tongue b of the rock dog forms a transverse gripping jaw or edge b which, in the form of construction shown in Figs. 1 to 3 inclusive, is provided with teeth as clearly shown in said figures. The bridge a when formed is raised into the position shown in dotted lines in Fig. 6 and in connecting the rock dog with the plate a the nose or tongue 6 of said rock dog is passed forwardly under said bridge after which, the said bridge is depressed into the position shown in full lines in Fig. 6, and this will secure the rock dog to the plate a, while permitting of its free movement.

The above operation may also be accomplished, and more easily in some instances by simplypulling on the end 0 of the belt or strap, this operation serving both to tilt the dog and pull the belt or strap through the buckle, and it will be observed that it- Patented Nov. 19, 1912.

point of fulcrum of said dog whereby two rocking centers or points for said dog are produced which makes this operation of the device possible.

In Fig. 3 I have'shown the method of using my improved buckle in connection with a belt 0, and in this operation one end of the belt is passed through the slot a andsecured in the usual manner, while the other end 0 of the belt is passed forward through the buckle or between the rock dog I) and the plate a. This operation raises the rock dog according to the thickness of the belt while at the same time permitting of its free movement. The end 0 of the belt may be passed easily and conveniently through the buckle as shown in Fig. 3 or in the direction of the arrow X, and the jaw I) of the nose or tongue 6 of the rock dog will grasp and hold saidend 0 in any osition into which it may be adjusted, an no amount of backward pull on the belt or a pull in the direction of the arrow X will release said belt or cause it to slip through the buckle. When itis desired, however, to adjust the belt in the direction of the arrow X all that is necessary is to place the thumb or a finger on the transverse head 6 of the rock dog and press said head toward the plate a or toward the stra and this will cause a rocking movement 0'? said dog which will release the clamping action of the jaw bi on the belt and-said-belt may be easily moved in the direction of the arrow X and if it be desired at any time to tighten said belt all that is necessary is to grasp the end a and pull it through the buckle to the desired extent, this operation resulting in lifting or'raising the jaw b. and permitting the belt to slide freely in the direction of the arrow X.

In Figs. 4 to 6, inclusive, I have shown a slight modification in which the plate a is provided with a supplemental transverse slot or opening a between the slots or openings a and 0a and with this construction thejawb of the nose piece or tongue I) of the rock dog operates in said slot or opening, and when in use the end portion 0 of the belt-is forced downwardly into said slot or opening as clearly shown in Fig. 5, and this form of construction is particularly adapted for use when, the jaw b is not provided with teeth.

In the construction shown in Fig. 7, the

strip a is provided with holes 0 and the jaw b of the dog?) with a central pin or tongue b adapted to enter said hole and in this form the operation of my improvement is somewhat similar to that of an ordinary buckle.

It must be understood that while the dog bis free to move both forwardly and backwardly to a slight extent undo the'bridge a and is also capable of slight movement toward and from the late a, it cannot be detached from said p ate whenonce concnected therewith as herein shown and described, and while I have shown my improved buckle as used in connection with a belt it will be'understood that said buckle may be used wherever such devices are required, as in connection with trousers straps, suspender straps, harness straps, or the straps of various other articles, and while- I have called the part a a plate stamped from sheet metal it will be understood that this part constitutes or forms the body or framework of the buckle and may be made in any way.

Having fully described my invention,

Letters Patent, is

A buckle, comprising a body member having on its back side a transverse bridge, and a rock dog loosely mounted between said bridge and the body member, the central portion of said rock dog being curved inwardly toward said body member and forming a pivot or fulcrum, edge portion thereof is curved outwardly and inwardly to form a jaw, the rear edge portion of said rock dog being curved outwardly and extended laterally to form a wardly of the said pivotpoint or fulcrum with side ears which are inwardly directed. and adapted to bear on the body member and which form another pivot point or ful otal points for. said dog are produced between the ends thereof. In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 26th day of August 1911.
